Physical and digital infrastructure are no longer separate domains. Transportation networks depend on communications networks. Digital and data infrastructure depends on power systems and supply chains. Water utilities rely on sensors and operational technologies. As these systems become more interconnected, artificial intelligence is increasingly coordinating how they are planned, operated, and maintained.
Infrastructure has evolved into an interconnected operating system; so the institutions responsible for it should evolve too. Infrastructure leaders are being asked to look beyond building more assets, toward financing, delivering, operating, and protecting these increasingly interconnected systems.
Deloitte’s 2026 Future of Infrastructure Survey sheds light on this shift. Infrastructure leaders surveyed across various regions expect increased investment across a wide range of infrastructure asset classes over the next three years. However, the defining challenge is no longer simply deciding what to build. According to respondents, governments also need to determine how infrastructure priorities can be financed, delivered, operated, and secured to account for the growing interdependencies across sectors and jurisdictions. Moreover, the survey also highlights the scale of this ambition, as well as the distance between it and the current delivery capacity.
While infrastructure systems are becoming more integrated, many of the institutions responsible for planning, financing, regulating, and delivering them remain organized around individual assets and sectors. Today’s infrastructure challenges increasingly stem not only from engineering but also from the organization’s ability to manage complexity across connected systems.
